Jim, a rabbit scientist, counted cottontail rabbits in the field during this time of predator hunting. 2. lected bearing on various phases of cottontail ecology. In contrast, a female cottontail rabbit will have a litter size of approximately 5. Match the population data for each species with the graph and the description and you’ll be able to sort it all out.

In what year/generation does this population reach its carrying capacity? This quiz and worksheet combo can help you quickly assess your knowledge of population ecology characteristics. Based on the growth curve of the rabbit population, what might have happened if a group of predators moved into the rabbit’s habitat during the 10th generation? Most bat species are likely to produce one offspring per year. During the summer months, cottontails primarily eat grasses, legumes, succulent annuals, weeds, as well as the occasional garden vegetable. 1. The winter diet includes small grains, as well as twigs, bark, and buds of shrubs and trees. 20 0 obj <>stream Rabbits, like quail and most other small game, have a high annual turnover rate — up to 80 percent of the population each year — which occurs regardless of whether they are hunted. Orient students to Part 2 and 3 by explaining that: “A population graph shows what happens to the population of a certain species over time. Species. Designed to reinforce basic topics in ecological population growth. Each population has a unique physical distribution in time and space. The mountain cottontail is native to much of the western portion of the contiguous United States (Hall and Kelson 1959:261). Population growth can follow either a J curve trend or an S curve trend. Landau's project, which included a children's story, compared population fluctuations of cottontail rabbit and pocket mouse populations.

Disease such as tularemia might also have an impact. Studied in a laboratory test tube over several (2nd population) weeks. A population is a group of individuals (all members of a single species) who live together in the same habitat and are likely to interbreed. In a J curve model, the population will continue to grow even when it has reached capacity. Population Ecology: The Texas Mosquito Mystery •What factors drive population growth? A female cottontail rabbit begins reproducing by one year of age and typically has 3-4 litters of 4-5 baby rabbits each breeding season. They then graph the data and observe the differences between exponential and logistic growth. 4.

Designed to reinforce basic topics in ecological population growth. They prefer brushy habitats that they can use to hide from danger, and they can also outrun many predators. Yet because they are so often preyed upon, and also fall victim to disease, a cottontail’s lifespan rarely lasts longer than a year. Bacteria X A common bacteria found in soil.
